Using Content Size Fitter or Vertical Layout Group causes error

UI

-

When using the Content Size Fitter OR the Vertical Layout Group components on the Content of a Scroll View, and playing the scene an error pops up:

Trying to add (Layout Rebuilder for) Content (UnityEngine.RectTransform) for layout rebuild while we are already inside a layout rebuild loop. This is not supported.
UnityEngine.Canvas:SendWillRenderCanvases()

2. How we can reproduce it using the example you attached:
See the attached video.

1. Create a Scroll View add Text GO to its Content
2. Add the Content Size Fitter component on the Content
3. Press play
4. Notice the error. Exit play mode
5. change the attributes of the content fitter: Fit - minimum size
6. play again
7. Notice the content size is now fixed
8. set the attributes of the content fitter: Fit - Unconstrained
9. play again,
10. the content size is still fixed

    Fixed for me 5.3.4. It's nice to see a clear console! Thanks Unity.

    It seems a fix for this issue is in the most recently patch release: https://unity3d.com/unity/qa/patch-releases/5.3.2p1

    That means it should be in 5.3.3 as an official release

    I'm still getting this on 5.3.2. Haven't tried any of the patches though.

    Is there a fix/workaround?

    This issue is NOT a duplicate. Please see repro steps.

    I was able to work around this by setting the scrollbar's Visibility to "Permanent" rather than having it appear only when content overflows. Not great.

    Turning off 'Pixel perfect' on canvas SOLVED the issue for MY project- far from optimal solution tho!
